Hi all, 3 months ago I bought a new Samsung T350 monitor, but I have some weird patterns (vertical lines, flickering, and things like “ghost screen”) on the screen. I discovered that appears sometimes only when I use the terminal on XFCE with NVIDIA proprietary drivers.

What I tried (when the problem appears):
• Power off and unplug it from the power monitor and pc.
• Disconnect the HDMI cable.
• Connect the monitor to another pc.
• Reboot into windows.
• Enter the UEFI

In all cases, the problem persist, so I think the problem is the monitor, because others monitors doesn’t have that problem, and when the pattern appears, the only solution is to wait around 20-30 minutes until they disappear and everything returns to normal. But on the other hand, I tested it on Manjaro KDE (proprietary drivers) and Xubuntu and Manjaro XFCE (open source drivers) and I don’t have that problem. The strange thing is that the trigger of the problem is only Manjaro XFCE with proprietary drivers, in addition, it also happens in the live usb.
Does the terminal cause the monitor (which could have a manufacturing defect) to fail? Any ideas?
Thanks
